Dedicated Electronics battery Lithium

Started out with Livescope LVS 32 and Echomap Ultra 126, added a 93SV shortly after when they went on sale.

Since then the 10 in Ultra's kept going on sale and I added 2 of those and removed the 93SV, also added a second LVS 32 I got from a member on here.

I had 2 group 27 Duracell AGMs from Sam's Club had them hooked up with a switch to just be able to turn the switch to change batteries. One of the batteries started only being able to handle the load for a couple hours.

Decided to bite the bullet by going to a lithium battery for the electronics. Debated on going with a 100ah or 125ah battery. Ended up with an Ionic 125ah battery. Buy once cry once.

Yesterday was the first day out with the new setup, got on the lake at 7am and put the boat back on the trailer at 630pm. Spent probably 9 hours actually fishing, the rest of the time was a little tour of the lake with the grandkids when they came around noon. Two of them wanted to go swimming after the tour the other just wanted to catch a fish. His dad and took him out on the boat, he fished for about an hour and didn't want to quit when it was time for them to leave. Pretty sure it helped that he was catching fish on a regular basis. Close to 15 in that hour, mostly small bluegill and a decent crappie that went in the livewell.

I checked the new battery with the bluetooth app a couple times during the day, amp draw was mostly around 8 amps with all the electronics running. End of the day it was at 35%, math works out to 80 amps used. That tracks pretty well with what I was seeing for amp draw of right around 8 amps with everything running. Didn't have the livescopes on for the lake tour with the grandkids.

Yesterday was a marathon trip for me so I don't see where I'll ever need to test how long the battery will power everything. The math says 15.6 hours , don't think my body can do that in one shot.
